The one-way EPR steering has been observed for both continuous variable (CV)
[1]}, [2]}, [3]}, [4]}, [5]} and discrete variable (DV) systems
[6]}, [7]}, [8]}, [9]}. Gaussian states and Gaussian operations
play a central role in the analysis and implementation of CV quantum
technology [10]}, [11]}. When considering generally bipartite Gaussian
states and using Gaussian measurements, the steerability between the
submodes is referred as Gaussian steering. What's more interesting, it has
been shown that the direction of Gaussian EPR steering can be manipulated in
noisy environment [4]}. The temporal quantum steering and
spatio-temporal steering have also been investigated [13]}, [14]}, [15]}.
Very recently, the EPR steering using hybrid CV and DV entangled state [16]} and remote generation of Wigner-negativity through EPR
steering [17]} are demonstrated. As applications, EPR steering
has been identified as an essential resource for one-sided
device-independent quantum key distribution [18]}, [19]}, [20]},
quantum secret sharing [21]}, [22]}, secure quantum teleportation [23]}, [24]}, [25]}, securing quantum networking tasks [26]} and
subchannel discrimination [27]}, [28]}.
